Coulomb's Law

Coulomb's Law
Any two point charges exert a force on each other that is proportional to the product of their charges, and inversely proportional to the square of the distance between them. This interlinks with the force of gravity as its strength weakens by the inverse square law as well.

This is Coulomb's law where Q1 and Q2 are the charges excerting a force on each other and K is the electric constant.

How Gravitational and Electric fields compare
The table below summarises some of the similarities between gravitational and electric fields. As you can see the similarities shown indicate that these fields have many aspects eg. equations that are almost the same but just take different quantities into account.
